NEW thread, no a hijacked one, as I give up searching for what I may have done WRONG
GPG error: http://www.deb-multimedia.org testing InRelease: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 5C808C2B65558117 The repository 'http://www.deb-multimedia.org testing InRelease' is not signed. After switching between testing and stretch .org and .org/dists I have given up. Something with gpg and keyrings is messed up and can't find out what it is. The rest of the debian repositories work and everything is current and updated. http://www.deb-multimedia.org testing does not have a Release file http://www.deb-multimedia.org/dists testing Release' does not have a Release file The repository 'http://www.deb-multimedia.org/dists testing Release' does not have a Release file. I just browsed into the directory and it DOES have a Release file right there. So I switched testing to stretch which appears to be the same Updating from such a repository can't be done securely, and is therefore disabled by default.See apt-secure(8) manpage for repository creation and user configuration details. The repository 'http://www.deb-multimedia.org/dists stretch Release' does not have a Release file. In the instructions it says once you open the directory download the multimedia keyring DUHHH....... !! But can't reach that repository because it is not signed as legit! -- "The most violent element in society is ignorance" rEG
